Influence of the PCB attachment on the mechanical properties in modal analysis

This paper is dealing with the influence of the electronic board attachment on its mechanical properties during the vibration load. Different number of screws and their position is investigated through the simulation in Ansys Workbench program. Setup is also verified by the measurement on the vibration table, where the sinus sweep from 10Hz to 2kHz with the 0,3g amplitude will be used. Moreover, virtual model will be created for the bare PCB as well as for the component board and the results will be compared. In conclusion, there will be defined the main parameters affecting the PCB mechanical properties.
